What is the primary stimulant found in coffee?

Reyn , me too

I love my coffee

Dorothy, You....

THERE ARE OTHER THINGS THAT HAVE CAFFEINE IN THEM.

the problem I have with caffeine they had it keeps you awake and alert well ok that go along with that, you work hard and you want to keep going by working etc, but then it says to much caffeine is bad for you. so why sell it when in truth it is said that too much can lead to this and that. it is puzzling....

little b, why doesn't every one drink at night

I sometimes drink coffee

Coffee plus alcohol , the base for a yummy Irish coffee . Add sugar , whipped cream, and enjoy.

I'm not allowed to drink caffeine at night 😴
